Propchange is/will be a module and service to simply answer the question:
If property X of document Y changes, what other documents are affected by this?
This question sounds simple, but if you have millions of documents from multiple sources, its not that easy.
The module/service has a simple interface. It is planed to have multiple backends to perform this task. Currently only a MySQL backend exists. Also, currently it's just a module, no standalone service.
- Simple "Detector" interface
- MySQL backend
- In-Memory backend
- More backends
- Standalone service
- SQS integration
- REST and or other Web API
